John Jacob Astor, 1st Baron Astor of Hever, was the second son of the first Viscount. This peerage (created 1956) was a separate creation and not to be confused with the Viscount's subsidiary title of Baron Astor, of Hever Castle in the County of Kent. The Hon. David Astor, the Hon. Michael Astor and the Hon. Jakie Astor, younger sons of the second Viscount, all gained prominence in public life.
